Abstract:
Lower semicontinuity results with respect to weak- convergence in the
sense of measures and with respect to weak convergence in
are
obtained for functionals
where admissible sequences satisfy a first order system of PDEs
. We suppose that
has constant rank, f is
-quasiconvex and satisfies the non standard growth conditions
with for

for
p>N-1. In particular, our results generalize earlier work where
reduced to
